IPC: B23Q3/15
Filed: 1984-01-17
Abstract: PURPOSE:To obtain a uniform magnetic chuck by burying a permanent magnet into the face plate which contacts with a workpiece and leading the magnetic flux of the permanent magnet and the induced magnetic flux by the electromagnetic coil of a chuck body to the electromagnetic-coil side. CONSTITUTION:When the attraction action by the magnetic flux phip due to a permanent magnet 4 and the attraction by the magnetic flux phie1 due to an electromagnetic coil 2 are performed, a workpiece can be strongly attracted onto the face plate 3 of a chuck body 1. When the exciting current of the electromagnetic coil 2 is reversed, a magnetic flux phie2 is generated in the direction for leading the magnetic flux phip due to the permanent magnet 4 towards the coil iron core side, and the magnetism of the permanent magnet 4 is increased, and the relation phip phie2 is established. The magnetic flux generated by the electromagnet 2 is desirably the magnetic flux in the degree in which the face plate 3 can be a little excited phie3 reversely, and the magnetism of the permanent magnet 4 can be also increased. Therefore, the generated magnetic flux of the electromagnetic coil can be utilized even in attraction, and a uniform magnetic chuck free from the part where the magnetism on attraction is weak can be obtained because of the permanent magnet.
